Right sided Dry Eye and Hypersalivation

Sounds like it needs a parotid duct transposition - and fix both problems

It is a possibility, it may just be very mild - normally the cases I see it's much more obvious and there is a real droop to the affected side's lip, and there's nothing in this case. I spent about 5 minutes just staring at this dog's face from various angles and couldn't see a difference! Even when he yawned it seemed symmetrical.

I rechecked the ear, which externally seemed fine but as David said could be Otitis Media/Interna so I've started him on antibiotics.

Forgive me doubting you Anthony, but are you sure about no paresis? Say that the right sided salivary glands were overproducing; with a normal mouth, wouldn't the saliva would just flow round and be swallowed in the normal way? Or is it only dribbling when the mouth is open?

[quote user="David Mills"]Facial nerve paralysis. Quite common with inner ear disease, but can be idiopathic or due to trauma. Causes reduced tear production so not true dry eye. Drooling due to paralysis of muscles around mouth not hypersalivation. Dry nose due to reduced tear production. Idiopathic common especially in old golden retrievers. [/quote]

I thought this initially too, but there is no facial paralysis though, no facial asymmetry, no drooping lips, palpebral response is normal, dog can blink and has a menace response. Ears are a little dry but no infection present.

Yes I was going to say the same a couple of days ago (but wasnt sure if I was being stupid) if you were sure the hyper salivation wasn’t actually saliva drooling due to paralysis of the lips on that side

What David says! Yesterday had a staffie with VII damage, no blink and was reading about VII being involved in tear production (despite knowing the OOOTTAFVGVAH mnemonic I can't remember which bit does what). No blink is something I've not seen before in VII damage from ear infection (or surgery). I suspect I haven't specifically looked.

May or not resolve. Treat with long course abx. Eye lube. May end up with enucleation or lifelong meds.

Can it blink?

Sounds like neurogenic dry eye. Ciclosporin pointless in these cases, can try pilocarpine but side effects are apparently quite frequent and not nice. Can't say about the hypersalivation.

I've seen similar in a Frenchie a few months ago, he was also staggering to the same side with a slight head tilt but no nystagmus. Bears some resemblance to IVD and Horners. Went as an emergency to the OOH provider but no diagnosis was made although IIRC they gave him some antibiotics in case it was otitis media. It has gradually resolved with no specific treatment but a very slight head tilt and lower lip droop have persisted.

Presumed to be some neurological issue related to being brachiocephalic but maybe someone who knows more about neurology will be along soon to help us.
